Redundancy: Interdependencies: How is redundancy applied to interdependent mechanisms?Options:Option 1: Interdependencies should be ignored.Option 2: All components and systems should be treated equally. Option 3: Only internal dependency analysis should be undertaken. Option 4: Interdependency analysis and proper planning for interdependencies should be done. Decision:IF no business continuity or disaster planning is done, THEN Interdependencies should be ignored.OTHERWISE IF there are a small number of systems and mechanisms or everything operates with the same risk profiles, THEN All components and systems should be treated equally. OTHERWISE IF the enterprise is medium or smaller in size information technology is medium risk or below, THEN Only internal dependency analysis should be undertaken. OTHERWISE Interdependency analysis and proper planning for interdependencies should be done. Basis:Interdependencies should be ignored.If no business continuity or disaster planning is done, it is likely that no interdependency analysis will be required either because the time and effort spent in analysis will not be applied to provide for recovery or continuity, and this is typically the most important reason to apply it. All components and systems should be treated equally.
Only internal dependency analysis should be undertaken.
Interdependency analysis and proper planning for interdependencies should be done.
